"Between 1960 and 1973, Leitz (Leica) patented an array of autofocus and corresponding sensor technologies. At photokina 1976
, Leica had presented a camera based on their previous development, named Correfot, and in 1978 they displayed an SLR camera with fully operational autofocus. The first mass-produced autofocus camera was the Konica C35 AF
, a simple point and shoot
model released in 1977."
Autofocus does not seem related to the H camera, and I'd guess the AF reference earlier in the thread may have been meant to be auto exposure.
